100 ohm Pt RTD or 0-900 ohm input ◆ 4-20mA output (sink/source) ◆ 12-32V DC loop/local power
Advanced signal processing capabilities, variable
range input, and convenient USB programming
make this instrument a very versatile temperature
measurement device. These transmitters can
withstand harsh industrial environments and
operate reliably across a wide temperature range
with very low drift. They feature RFI, EMI, ESD,
EFT, and surge protection plus low radiated
emissions.
Description
The TT231 model is a space-saving two-wire
transmitter that converts a 100 ohm Platinum
RTD sensor input to a proportional 4-20mA
signal. Power is received from the output loop
current or a DC supply when using a three-wire
connection. The transmitter provides sensor
excitation plus performs linearization, lead-wire
compensation, and lead-break detection.
Key Features & Benefits
Setup and calibration are fast and easy with
a convenient USB connection to your PC and
Acromag’s Windows configuration software.

4-20mA output, upscale break detection.
Input Configuration
Two-, three- or four-wire sensor input connections.
Input Ranges
100 ohm Platinum RTD, alpha = 375-393,
385 (default), -50 to 900°C (-58 to 1652°F).
0 to 900 ohms linear resistance.
Programs in °C, °F, or ohmic integer values only.
Zero Adjust
RTD 3/4 wire: -50, -17.78, or 0°C (-58, 0, 32°F).
RTD 2 wire: 0°C (32°F) fixed.
RES: 0 or 100 ohms.

■ Output
Output Range
4 to 20mA DC.
Under-scale limit adjustable for 2.1 to 3.6mA, nominal.
Over-scale limit adjustable for 21 to 30mA, nominal.
Output Fault Limits (Sensor Fault)

1.0mA above over-scale threshold, typical.
Output Compliance
RLOAD = (VSUPPLY - 8.6V) / 0.020A.
RLOAD = 0 to 750 ohms @ 24V DC.
Output Accuracy
Better than ±0.1% of span, typical for spans less than
500°C. Includes the effects of repeatability, terminal
point conformity, and linearization, but does not
